A friend told me, that his brother (tru story) is a photocopy repair tech.

He said that his brother told him that as copy machines are business items & must work 100%, 100% of the time.
To do that they are programmed to shut down for service every so many copys & they are overbuilt & under the rated output.

ie, the machine shuts down at something like 85% of the possible output of 100% quality copys for servicing.

With the right codes, the machine will start up & run the last 15% of the copys. Thats at 100% quality. After that the machine will still go on to do as much as another 30% more than what it was made to do in the first place.

Add in the free parts, such as toner, belts & drums etc & the machine can do as much as 200% more over time with the odd unofficial servicing, for very little expense.



It might pay to ask around to find a copy service tech with some spare time up his sleeve.

In my experience metal engineering workshops like old photocopiers, they can copy off drawings, shoot them out to the workshop & they don't have to worry about damaging the drawings with dirt, sparks & fire.
